METHOD TO IMPLEMENT E911 SERVICES IN IMS (IP MULTIMEDIA SUBSYSTEM)
First Claim
1. A system for processing emergency calls in IMS (IP multimedia subsystem), comprising:
- a profile fetching component that queries a data store within the IMS for an E911 (Enhanced
911) profile associated with a user when an emergency call is received from the user; and
a routing component that routes the emergency call to a PSAP (Public Safety Answering Point) determined based in part on an analysis of the E911 profile.

Abstract
A system and method that facilitates processing and/or routing of emergency call in an IMS (IP Multimedia Subsystem) for VoIP (Voice over IP) subscribers is provided. Specifically, an E911 profile is generated, for example, by an application server, for each VoIP subscriber based in part on current location information associated with the subscriber, such as, the subscriber'"'"'s IP address. The E911 profile is pushed to the HSS (Home Subscriber Server) of the IMS. The E911 profile can then be stored in the HSS and can be queried by an E-CSCF (Emergency Call Session Control Function) during emergency call processing. Moreover, when an emergency call is received from the subscriber, the E-CSCF can retrieve the E911 profile associated with the subscriber from the HSS and route the call to an appropriate PSAP (Public Safety Answering Point) based on an analysis of the information in the E911 profile.
